This standard prescribes the nomenclature, requirements and test methods for electronic grade solder alloys; for fluxed and non-fluxed bar, ribbon and powder solders for electronic soldering applications; and for ‘‘special’’ electronic grade solders. This is a quality control standard and is not intended to relate directly to the material’s performance in the manufacturing process. Solders for...

The IPC-2581C standard specifies the XML schema that represents the intelligent data file format used to describe printed board and printed board assembly products with details sufficient for tooling, manufacturing, assembly, and inspection requirements. This format may be used for transmitting information between a printed board designer and a manufacturing or assembly facility. The data is most...

The IPC-CC-830C standard establishes qualification and conformance requirements for electrical insulating compounds (conformal coatings). It has been designed and constructed with the intent of obtaining maximum confidence in the materials with minimum test redundancy. The IPC-CC-830C standard covers: • The qualification and qualification retention of the conformal coating material (Table 3-1...

This document standardizes the requirements for power conversion devices (PCDs) for the computer and telecommunications industries. The phrase “power conversion devices” refers to ac to dc and dc to dc modules, converters and power supplies. This specification sets the requirements for design; qualification testing; conformance testing and manufacturing quality/reliability processes, but does not...

This document includes lead free, no-clean, and environmental friendly chemistries. This is a collection of information on electronic board and assembly cleaning in a single location. This major revision explains the relationship between materials, processes, and contaminants in fabrication and assembly operations. It also addresses cleanliness assessment and process control in relation to...

The IPC-9701B standard establishes a thermal cycling test method to characterize the fatigue lifetimes of surface mount solder attachments of electronic assemblies. The surface mount devices may be solder-attached to rigid, flexible or rigid-flex printed boards. The characterization results can be used to predict the field lifetime of solder attachments for the use environments and conditions of...

The IPC-7801A standard provides requirements for process control of conveyorized solder reflow ovens. It includes a methodology for performing temperature measurements over time to establish a baseline profile, and then provides requirements to verify repeatability through periodic verification of the oven profile.

The IPC-7525C standard provides guidance for the design and fabrication of stencils for solder paste and surface-mount adhesive with much of the content based on the experience of stencil designers, fabricators, and users.

This document provides useful and practical information for developing thermal profiles to produce acceptable SnPb and Pb-free electronics assemblies using reflow, vapor phase, laser, selective and wave soldering equipment. The document also includes a troubleshooting guide for addressing common defects which can be attributed to profiling.

IPC-7526A handbook addresses understencil cleanliness during stencil printing, removal of solder paste from stencils following the cleaning process and misprint PCB board cleaning considerations.

Developed by the OEM council of the IPC, IPC-1720A categorizes electronic assembly manufacturer capabilities and supplies the OEM customer with detailed, substantive information. This program simplifies auditing processes and reduces the frequency of audits, thereby decreasing paperwork and improving efficiency. Company and Site Description, Site Capability Snap Shot, Equipment Profile (Pre-site...

Covers the information requirements for the procurement of material, box build, assembly, system integration, inspection, test, burn-in, delivery and/or distribution of electronic assemblies. 5 pages. Released January 2004.

This specification sets requirements based on performance criteria for the use of Immersion Silver (IAg) as a surface finish for printed circuit boards. It is intended for use by chemical suppliers, printed board manufacturers, electronics manufacturing services (EMS) companies and original equipment manufacturers (OEM). IAg is a thin immersion deposit over copper. It is a multifunctional surface...

This standard provides a marking and labeling system that aids in assembly, rework, repair and recycling and provides for the identification of: 1. those assemblies that are assembled with lead-containing or lead-free solder; 2. components that have lead-containing or lead-free second level interconnect terminal finishes and materials; 3. the maximum component temperature not to be exceeded during...

This standard establishes the requirements for timely customer notification of changes to electronic products and associated processes.

This standard is applicable to suppliers of, and affected customers for, electronic products and their constituent components. The goal of this notification standard is to better enable customers to manage and mitigate the disruption caused by the discontinuation of a product and to ensure continuity of supply. This standard establishes the requirements for timely customer notification of planned...

The IPC J-STD-004C WAM1 standard prescribes general requirements for the classification and characterization of fluxes for high quality solder interconnections. The IPC J-STD-004C WAM1 standard may be used for quality control and procurement purposes. Soldering flux materials include the following: liquid flux, paste flux, solder paste, solder cream as well as flux-coated and flux-cored solder...

The IPC-D-640A standard provides design and critical process requirements and technical insight for cable and wire harness assemblies incorporating optical fiber, optical cable and hybrid wiring technology. The IPC-D-640A standard is intended to provide information on the general design requirements for optical fiber, optical cable, hybrid wiring harness assemblies, and Fiber Optic Communications...

While there are a variety of industry test vehicles for the examination of material compatibility, the IPC-B-52 test board was created to meet the needs for testing both ion chromatograph and surface insulation resistance (SIR) which would be more representative of the manufacturing materials and processes.
